My tentative advice would be to find the one with the best reviews. Only pay attention to the lowest reviews, even a few 1-stars are informative.

My story: I brush and floss every single day. At my regular checkup, the dentist measured 2-5mm gum depths, and insisted on doing a deep cleaning, which involves anesthesia and multiple visits. I argued that the 5mm depths were borderline, and could very well be 4mm with measurement error. (They did seem to be pushing rather hard.) They also pointed out some tiny supposed "pockets" on the X-ray that looked like just imaging blur or something. Feeling very suspicious, I left, and found another dentist with, surprisingly, zero bad reviews on Yelp. They measured 2-4mm gum depths, and did a much less aggressive cleaning.
